Water-induced fluorescence quenching of mono- and dicyanoanilines

Photophysical properties of monocyano- (2-, 3-, and 4-cyano) and dicyano- (3,4-, 3,5-, 2,3-, 2,4-, 2,5-, and 2,6-dicyano) anilines are investigated by fluorescence measurements. All the monocyanoanilines are virtually nonfluorescent in water (quantum yield 0.01); however, in nonaqueous solvents (cyclohexane, acetonitrile and ethanol), the fluorescence quantum yield is enhanced substantially. In contrast, dicyanoanilines investigated are highly fluorescent both in aqueous and nonaqueous environments. The photophysical data and MO calculations suggest that conformational changes in the amino group and variation of hydrogen-bonding interactions between the solute and solvent water upon electronic excitation are responsible for the water quenching in the monocyanoanilines.

SULFONAMIDE DERIVATIVES

The present invention relates to microbicides for agricultural or horticultural use containing sulfonamide derivative of, for example, a formula (I):or a salt thereof,[wherein A1is (1) an aryl group which may be substituted or (2) a heterocyclic group which may be substituted, X1is (1) a chemical bond, (2) a methylene group which may be substituted, or (3) a vinylene group which may be substituted, B1is a five-membered heterocyclic group comprising nitrogen or sulfur atoms as the ring-constructing atoms except for carbon atoms and may be substituted or a condensed heterocyclic group which may be substituted, Z1is (1) a hydrocarbon group which may be substituted, (2) an acyl group which may be substituted, (3) formyl group, (4) an amino group which may be substituted, (5) a group represented by -N=CR1R2(wherein each of R1and R2is a hydrogen atom or a hydrocarbon group which may be substituted), (6) a cyclic amino group, (7) a group represented by -OR3(wherein R3is a hydrogen atom, a hydrocarbon group which may be substituted, an acyl group which may be substituted, formyl group or an alkylsulfonyl group which may be substituted) or (8) -S(O)nR4(wherein n stands for an integer from 0 to 2, R4stands for a hydrogen atom or a hydrocarbon group which may be substituted). The said compounds or the salts thereof are sulfonamide derivatives with microbicidal action, areuseful as excellent microbicides for agricultural or horticultural use, because they are safe, and they have little influence on human beings, farm animals, natural enemies, or the environment, and exert excellent control effects even on resistant microbes.
